Perhaps this belief stems from PSA posturing themselves as indeed being capable of doing precisely that and everyone just believing them, but it doesn't make it true. Unfortunately.

IMO the overwhelming majority of trimmed cards can be conclusively shown to be trimmed if forensically examined. Conversely, IMO, the overwhelming majority of trimmed cards cannot be shown to be trimmed by visual examination alone when altered by an experienced card doctor.
Inasmuch as (to my knowledge) PSA undertakes only visual examinations, the opinion it gives to any card where an uptick in grade equates to a significant bump to its market value, unless that card has documented provenance to a period before card doctors existed or there was no economic incentive to trim (or otherwise alter), is WORTHLESS.
So, the sin PSA is guilty of is not a failure to detect something that they could have detected, but their representation that a numerical grade gives a collector a reasonable assurance the card has not been trimmed.
